Population Density

Distributing to Blocks

Try to distribute exact population numbers to street block level where only rough categories are published

Merging with Hex

Now that we have estimated inhabitants on block level we merge that info with the hex grid.

We call the measure for how inhabited a grid cell is weight

Test Centers

Now we add the test centers to our grid

For grid cells with a test center, we set travel time to 0

For grid cells in the direct neighborhood, we set travel time to 1

Travel Time To Test Centers

For grid cells where we don't have a test center, we calculate the travel time with public transport to the nearest cell with a center.

Putting it all together

Now we combine number of inhabitants with travel time to the nearest test center for some kind of "fairness measure" or a visualization where test centers are missing
